摘要： An analog-to-digital converter (ADC) is described. This ADC converts an analog signal into a digital value using a two-pass digitization process. In a first operation, coarse digitization is performed by an averaging converter based on a set of references. Then, in a second operation, fine digitization is performed by either another averaging converter or the same averaging converter based on a subset of the set of references that is progressively closer to an instantaneous value of the analog signal. For example, the coarse digitization may be performed by a low-resolution ADC stage and the fine digitization may be performed by a sigma-delta ADC, such as a single-bit sigma-delta ADC. Moreover, the other averaging converter may use dynamic element matching to shuffle reference elements used to generate the subset. In this way, the ADC may provide high resolution with reduced nonlinearity and quantization noise.
摘要翻译：描述了一种模拟 - 数字转换器（ADC）。该ADC使用二次数字化处理将模拟信号转换为数字值。在第一操作中，基于一组参考的平均转换器执行粗略数字化。然后，在第二操作中，基于逐渐接近模拟信号的瞬时值的参考集合的子集，由另一个平均转换器或相同的平均转换器执行精细数字化。例如，粗略数字化可以由低分辨率ADC级执行，精细数字化可以由诸如单位Σ-ΔADC之类的Σ-ΔADC来执行。此外，另一个平均转换器可以使用动态元素匹配来混洗用于生成子集的参考元素。以这种方式，ADC可以提供具有降低的非线性和量化噪声的高分辨率。
